Chapter 2. Initial Setup
2.5 Activating a Channel
The
Channelx-ACTIV
submenu permits selection of the desired measurement method. In addition, it is used to
activate/deactivate one or both of the channels in a 2-Channel Model XGM868i.
To access the Channelx-ACTIV submenu:
1. From the Keypad Program, scroll to
CH1
or
CH2
and press
[Enter].
2. In the
Channel PROGRAM
menu, scroll to
ACTIV
and press
[Enter].
3. Scroll to Burst to activate the channel/path, and press [Enter] .
Note:
Burst is automatically selected for a 1-Channel meter.
4. Scroll to one of the measurement methods described below and press
[Enter]
.
•
Skan Only is the preferred technique for locating the acoustic signal and for high velocity measurements. It is
more robust in a noisy environment than the Measure technique.
•
Skan/Measure is the preferred technique to use for low velocity measurements.
If Skan Only is selected at the above prompt, the meter uses this technique exclusively. However, if Skan/Measure is
selected, the meter uses Skan Only to find the acoustic signal and then tries to use the Skan/Measure technique for the
actual measurement.
After completing the above step, the meter returns to the
Channel PROGRAM
window. Proceed to the next section to
continue programming your meter.
